The movie Frozen inspired the icy, 3-D printing of blood vessels
Ice guides a 3-D printing method to make realistic, artificial blood vessels. One day, such vessels could be used in lab-grown organs.

Rampaging vines are slowly strangling tropical forests
Called lianas,these vines are growing out of control. They may cause tropical forests to absorb less carbon dioxide — worsening climate change.

Balsa wood transistors could usher in ‘greener’ electronics
Researchers in Sweden coaxed wood to conduct electricity, then used it to make a climate-friendlier building block of electronics.
